This is a modest custom-built Hi-Capa 5.1 in-house at BlackBlitz Airsoft. Based on a Tokyo Marui 5.1 Hi-Capa, the slide has been upgraded with a full metal Guarder Aluminum Nighthawk slide kit, featuring an elegant design with serrations and markings. The outer barrel, chamber, spring guide, and spring guide cap has been replaced with a Guarder stainless and non-stainless steel parts for improved durability. Internally, the pistol has a PDI 70° w-hold bucking with a PDI 6.01 tightbore inner barrel for unmatched accuracy, range, and airseal. The hopup unit and nozzle have been upgraded with Cowcow and Gunsmodify parts respectively to provide a comfortable edge over the stock assembly. On top of the stellar performance already offered by the 5.1 Hi-Capa, the pistol is also outfitted with a Guarder 150% enhanced recoil spring and short stroked for even crispier blowback and cycling. This is a one-of-a-kind, rare custom pistol. All parts and upgrades have been professionally installed and fitted for premium performance. Its functionality and quality of labour will be fully ensured by us.
